These are the brushes I use most often. I use some super basic ones too, like a simple soft airbrush and a simple circle brush, but you don’t need a guide on how to make those.
Some of the blotmaps and textures are from this pack.
I don’t take credit for any of the shapes or textures in the pack, I have borrowed them all from other artists. If I ever get around to making my own custom blotmaps or whatever, I will let you know.
The top left one is best for blotchy-but-smooth painting. It will give a sort of impressionist feel (sorta).
The top right is a “pencil” tool. It does what it sounds like.
Bottom left is fantastic for loose textured speed painting. It will force you not to over-blend things so if you have a habit of painting everything “too smooth”, this will force you to like… not do that as much.
Bottom right is good for achieving a nice wet-on-wet paintstroke look. I frequently use it for stuff like clouds, water, etc.
Note: I change the settings quite often. It depends on what you need really. Sometimes I end up changing them so much that I just make a new brush - that’s how the bottom right came about, it was originally just a copy of the top left.
